The president of Penn State University says a task force will examine aspects of fraternity and sorority life as police investigate photos of naked and semi-nude women posted on a Facebook page linked to a university fraternity.

More than 100 Penn State University students and other supporters demonstrated Friday against a fraternity accused of posting photos of nude or partly nude women, some asleep or passed out, on an invitation-only Facebook page, urging the administration to take stronger action against those involved.
